This article evaluates the historical performance of Chainlink integration and the replacement of Curve Pool EMA Oracle. It was found that the lack of reliable Chainlink data sources for collateral assets has impacted integration with the Prisma platform. The study proposes preliminary specifications for improving the Oracle to enhance price accuracy and reliability. Additionally, the research discusses the importance of the Oracle in Prisma liquidation and redemption processes. It is advised to use Curve's price oracle function with caution. Finally, a hybrid solution combining Curve and Chainlink Oracle is proposed to enhance the flexibility and reliability of the pricing mechanism. This report is applicable only to the Prisma protocol.

An oracle in blockchain technology is a third-party service that provides external data to a smart contract, allowing it to interact with the real world.

Maelstrom from Hayes Fund analyzed the current competitive landscape of the oracle market, particularly highlighting Flare as a unique oracle protocol that may be underestimated by the market. The article compared three key oracle protocols: Chainlink, Pyth, and Flare, noting that while Chainlink leads the market, it faces limitations in terms of latency and high throughput. Pyth focuses on financial use cases but lacks universality. In contrast, Flare combines Oracle systems with EVM smart contracts, providing both data and computational services, with validators responsible for providing accurate data to earn rewards. Flare's FTSO and data connectors are its core components, offering efficient data transmission and free data-feeding services. Although Flare lags behind Chainlink in terms of project integrations, its token economics and unique market positioning give it upward potential.

This article dives into APRO, an Oracle solution in the Bitcoin ecosystem. It explores how the solution delivers reliable off-chain data to the Bitcoin network and its key role in DeFi applications.

Since DeFi's emergence, the quality and security of on-chain data have been paramount concerns for developers, particularly regarding oracles—the critical bridges between on-chain and off-chain data that are often targeted by attackers. This article explores oracle use cases, common attack patterns, and prevention strategies for oracle manipulation. It provides practical guidance for developers on secure oracle integration while explaining their vital role in the blockchain ecosystem. Through analysis of recent incidents like UwU Lend and Banana Gun, we highlight how data reliability fundamentally shapes DeFi ecosystem stability.

Tellor is a decentralized Oracle protocol designed to provide reliable operational data for digital assets. It is widely recognized and supported in the cryptocurrency world as it offers a decentralized data solution, bringing greater reliability and transparency to DeFi.

Pyth Network introduces the Oracle Integrity Staking (OIS) mechanism, offering a new security measure for the DeFi sector. OIS incentivizes data providers to deliver accurate price data through staking rewards and penalties, protecting the DeFi ecosystem from unreliable data. This article explores how OIS functions and how it

Gate Research conducts an in-depth analysis of the oracle sector, exploring the strengths and strategic layouts of leading projects such as Chainlink, Pyth, and Redstone. It looks ahead to the second growth curve driven by RWA, AI, DePIN, and other factors, forecasting that the oracle market has a potential value of $23.1 billion. This article will examine the topic from four aspects: the development history of oracles, market size, core projects, and future development.

As a leading global F1 team, Oracle Red Bull Racing is always committed to pushing the engineering limits, and Gate.io, the innovator of blockchain technology, is also making continuous progress in the digital finance field. Recently, the two parties officially reached a long-term exclusive partnership. Gate.io will become the exclusive cryptocurrency exchange partner of the Oracle Red Bull Racing team, jointly exploring the integration and development of racing sports and blockchain technology.

This article provides an in-depth analysis of Angle Protocol's oracle design and its defense mechanisms against front-running transactions. By combining Chainlink and Uniswap V3 TWAP, Angle offers an innovative solution aimed at protecting the protocol from front-running attacks while ensuring users receive fair transaction prices.

NEST Protocol is a decentralized Oracle network that uses a unique "quote mining" mechanism to synchronize off-chain data with on-chain data without needing a central authority. NEST Protocol provides efficient and decentralized price information for various applications, including decentralized exchanges, financial derivatives, Metaverse, GameFi, and more, aiming to improve the transparency and reliability of decentralized finance.

Pyth is an efficient oracle protocol that provides reliable price data through a pull model. Similar to a push model, it delivers data to off-chain engines, providing price updates when on-chain requests data. Pyth has been adopted by several prominent projects such as Synthetix and Helium, and has expanded to serve the most diverse blockchains. The maximum supply of its ecosystem token PYTH is 10 billion, allocated to the community, provider incentives, ecosystem growth, protocol development, and private sales. Pyth's goal is to make all world financial market data available for Web3.

The existence of OEV has resulted in value redistribution among different stakeholders, and API3 claims to use an auction mechanism to make the OEV redistribution as reasonable as possible (allocated through market mechanisms), and try to bring faster and lower-cost price updates.
